In percentage, its success rate hovers around 0.1-0.2%, making it one of the toughest exams not just in India, but globally.

These numbers reflect that UPSC is not about the last-minute rush or inconsistent reading; it is about adopting a strategic approach. To which, you must start early on, be smart with book selection, keep tabs on current affairs, and most importantly, prepare a timetable that must be followed throughout.

Keep tabs on the Current Affairs

Current Affairs form the backbone of the Civil Services Exam. You can refer to good newspapers such as The Hindu or The Indian Express to answer the questions asked in UPSC. 

Also, if you are not the one who can spend 2-3 hours on the newspapers, then you can opt for the monthly magazines available online. Such magazines are properly segregated as per the prelims and mains. They can help you with crisp notes for prelims and a detailed explanation for the mains exam. 

Choose the Optional Subject Early-On
